ーガ機。 The auger shaft of the earth auger consists of an inner tube driven by a drive device and an outer tube with a screw fitted and supported on the outside of the inner tube. A rotation transmission mechanism is provided for forward and reverse transmission to the tube through play rotation at a predetermined angle, and the lower ends of the inner and outer tubes terminate at approximately the same position, and the lower end of the outer tube has a shaft stop. A plurality of shutter plates are provided as fulcrums, which can be opened and closed freely, close the lower end openings of the inner and outer tubes when closed, and open when opened. An earth auger machine, characterized in that it is equipped with a drive pin that opens and closes a shutter plate using a shaft stop as a fulcrum by moving in the rotational direction as the inner tube rotates freely.
